Operation Meetinghouse (bombing of Tokyo in March 1945) is estimated to have killed 100,000 civilians. Overall the air raids on Japan (led by the United States although British involvement occurred on a much lesser scale) killed anywhere from 241,000 to 900,000 civilians (although most modern estimates place the number between 300,000 and 500,000).
